Specification of Letters Patent.

Patented Jan. 2, 1%17.

Application filed April 8, 1913. Serial No. 759,785.

To all whom it may concern Be it known that I, JOHANNES CHRISTIANJonnxsnx, a subject of the King of Denmark, residing at 27 Nelbeckstreet, Cavendish Square, London, V, England, have invented certain newand useful Improvements in or Relating to Massage Apparatus, of whichthe following is a specification.

The present invention relates to massage apparatus of the stationarytype in contradistinction to those apparatus which are held in the hand,and although usually the apparatus will be used in a certain position,it is preferably made so that it can be adj usted, moved or eveninclined or turned on one of its sides.

The object of the invention is to provide an apparatus which shall becapable of use under all conditions and for all purposes for which themassage apparatus may be required and to so construct the machine thatwhile it is provided with a number of tools or applicators, or means forapplying a number of tools or applicators in different positions, themechanism is provided in a comparatively.small compass and issulliciently protected against damage or in terference while it ispreferably so mounted or arranged so as to be capable of being adjustedboth vertically (or horizontally) and angularly.

In its general form, the apparatus consists of a casing, which may be inthe form of a box, which contains the driving device or motor andvarious mechanisms for operating the tools or applicators which may beof the tapping and frictional kind, and which may be either permanentlyarranged in position with their operative surfaces extending out fromthe box, or may be made so as to be removable therefrom. A plurality ofholes for the stems of applicators, are arranged on one, or more sidesof the box or casing, and preferably one side and the top of the box areprovided with both tapping and frictional devices so that one or othercan be used according to whichever is the more suitable for the patient,as regards the position of the applicator and the parts to be operatedupon.

I preferably employ an electric motor C in the box 13, and supply itwith current by means of a flexible conductor G which passes through ahole in the bottom or side wall of the box, and the various motions forthe applicators on the top and sides of the box are all derived from themotor shaft.

Freferably the box or casing B is mounted in an open framework orsupport a standing a suitable height from the floor say about six feet,in which the box can be adjusted and held at any desired height from theground.

I will now describe a convenient embodiment of my invention, referencebeing had to the accompanying drawings, in which,

Figure 1 shows a front view of the complete apparatus, the uprightsforming the frame being shown broken; Fig. 2 is a side view of the upperpart of Fig. 1; Fig. 3 be ing a sectional plan; Fig. t is a plan view ofthe box or casing, partly in section, the lid or cover being removed;Fig. I is a vertical section of the box on the line AA of Fig. l; Fig. 6is a sectional side elevation on the line 13-3 of Fig. 5; Fig. 7 is adetail view of a construction of one of the frictional applicators;Figs. 8 to 13 showing diagrammatically six different positions of theapplicator relatively to the main stem; Fig. i l is a detail viewshowing how a quick tapping motion can be obtained; Figs. 15 and 16showing modifications in which double and treble speed motions may beobtained; Fig. 17 is a vertical section of the frame and box wherein thebox can be mo ed angularly as well as vertically; Fig. 18 is ahorizontal section of Fig. 17 taken above the box, Figs. 19 and 20.-show sectional side views on the lines C-C and l)l) respectively of Fig.17.

I I will first descrioe the apparatus in a general way, and then explainconstructional details.

Referring to Figs. 1, 2 and 3, the frame is formed of four verticalangle irons a forming guides for the box B. These angle irons aresuitably mounted on a base a, and connected at the top by a cover of,which may be removable. The inner surfaces of the uprights a arepreferably lined with leather or felt a or similar material, which willprevent wear of the corners of the box and at same time act as asilencing and shock absorbing material.

At the top of the frame is arranged a winding drum a provided with ahandle a, two cords a", a being connected to the drum at one end, theirother ends being secured to rods B secured to the sides of the box B.The drum (4 or its shaft, is provided with a toothed wheel a with whicha pawl a" engages for the purpose of pre\-'enting, .the box slidingdown, by reason of its weight, after it has been raised to the desiredhei ht by turning the handle a The standards may be so arranged, or atsuch distance apart, that it may be possible to introduce the body of apatient between them for treatment with one or other of the applicators.

The container for the driving and operating mechanism, of the massagetools or applicators is here shown as a rectangular box, entirely closedon all sides with the exception of certain small holes for the stems ofapplicators as will be described.

In the example illustrated, provision is made on the front of the box Bfor two rota tory frictional applicators attached to the stems (Z at thetop, two tapping applicators attached to the sockets at the middle and arocking member f carrying two applicators attached to stems near thebottom. On the top there are two tapping applicators, actuated by lever(Z and on one side there are also arranged two tapping applicatorsactuated by the rod e. Thus there are provided two kinds of frictionaltools on the front of the apparatus, as well as tapping tools, while thelatter kind of applicators are available both on the top and side of theapparatus.

The interior contents of the box will now be described, referringparticularly to Figs. 4, 5 and 6.

I secure centrally in the box to the bottom Z) an electric motor C,mounted on abase plate C. This motor is supplied with current by meansof a flexible conductor which enters the box through a hole in thebottom and is connected to the terminal The motor shaft is provided atthe back with a fly-wheel C and at the front with a crank for operatingtwo rocking levers D, E, from which the top and side tapping motions andthe front bottom frictional motion and central tapping motions arerespectively derived.

1 will first take the upper lever D. This lever is secured to anddepends from a l1OIl-' zontal shaft (Z mounted in suitable bearings cl,d on the upper part of the motor casing.

At its lower end the lever D is slotted at (Z (Fig. 5) to receive asliding block in which the crank pin (F of the motor shaft engages. Asthe shaft turns the lever D willbe rocked about the axis of the shaftcl, which, being keyed to the lever D, will also have imparted to it arocking or slight turning motion about its axis.

The shaft (Z has secured to it, toward its other end and about centrallyabove the motor, a cross bar (Z (Figs. at and provided preferably at itsends with rollers (Z As the shaft (Z rocks the two ends of the bar (Zwill, therefore, be moved alternately toward and from the top of thebox. Immediately above these rollers are arranged guides d, which extendthrough the top of the box, for the stems (Z of tapping applicators. Iprefer to construct and arrange these applicators in such mannerthattheir ends (Z are not acted upon by the rocking bar (Z until they areforced inward against spring pressure by the pressure exerted upon themby the body or part to be operated upon, as will be ex plained furtheron when the front tapping device is described. It will be seen that bythis device I obtain an alternate tapping action by the two applicators.

The tapping applicators on the side of the box are also operated fromthe lever D by means of a link 6 pivoted to the lever D at a suitablepoint between (Z and cZ (Fig. At its other end this link is pivoted to ahanging bar a pivoted at its upper end to a bracket 6 or other means ofsupport on the box. At its lower end the bar 6 carries a roller 6adapted to strike, when the bar is rocked, the end 6" of the stem 6 of atapping applicator. A second bar and applicator are similarly arrangedto the side of the bar 6, the two bars being keyed to a common shaft 6so that the two applicators are acted upon simultaneously when the bar 6is rocked by the link 6, which, in turn, is reciprocated by the rockinglever D as the motor shaft rotates.

The mechanism for operating the applicators on the front of the box willnow be described. At the top (see Fig. 1) are provided means forreceiving two rotatory frictional applicators, which are driven bygearing, here shown as arranged at the back of the motor (Figs. at, 5,and 6). This gearing consists for instance of a train of wheels 9', g, gg 9 g? the wheel 9 being keyed on the motor shaft and the otherssuitably mounted on the back of the box, the wheel g gearing with twopinions g, g,

fast and horizontal shafts 5/ extending right across the top of the boxand projecting through the front wall, as shown in the left handsectional part of Fig. 4. The two shafts will thus both be driven at thesame slow speed of rotation, although by making slight space,

i manner as the similar the wall of the box. Thus,

that purpose in out the securing screws the in the bearing and on thestem respectively,

in which a spiral spring 9 is confined, this spring having a tendency topress stem and head outward.

A collar 9 is secured, as by a set screw, to the inner end of the stem 9A corresponding collar 9' is secured to the shaft g in such positionthat the opposed faces of the two collars are normally separated by aand their faces are provided with leather or other suitable surfaces. Itwill now be seen that as long as no pressure is exerted on the head gthe motor may be running and the shaft 9 rotated without any Tdrivingeffect belng produced on the stem and head, but as soon as pressure 1sexerted against the applicator secured to the head 9 the latter is movedinward, against the spring 9 until the two collars or friction disks 9 gare pressed together, whereuponthe motion of the shaft 9 is imparted tothe stem and head and through them to the applicator which thus rotateswith them.

The action and function of the lever E, which is also rocked by thecrank pin of the motor shaft will now be explained. This lever canoscillate about the axis of a shaft 7 to which it is secured at itslower end, its upper end being slotted and engaged by the crank pin d*(Fig. 5) which thus acts upon both levers D and E. This shaft 7 extendsout through the front wall of the box (Fig. 4:) in order to receive,from the outside, a rocking applicator bar or holder f. This holder issecured to or provided with a tubular stem 7 fitting over the shaft 7and provided with spring f and friction collar or disk 7, adapted toengage a corresponding disk 7" on the shaft f, in exactly the same partsalready described with reference to the rotatory applicator holdersdriven by the train of gearing may be runr r Thus the motor shaft unlessning but the member f will not rock the applicators therein are in usei. 6., being pressed against the part to be treated.

The bar 1s, as shown in Fig. 1, slotted on either side of its center toreceive pins- 6 to which the tubular stems of applicators can besecurec. These pins are provided with collars f and lock nuts f as shownin Fig. 4 whereby the pins can be secured in any desired position in theslots. By moving the pins farther away from/or nearer to the middle ofthe bar a more or the V of the apof the less extended curvilinear motionplicators, in a plane parallel to that front of the box, can beobtained.

There now remains to be described the operation of the tappingapplicators on the front of the apparatus. These are derived from thelever E in the following manner 1-- At a suitable point on the leverlugs it, h are formed having a connecting pinh. An upright shaft isjournaled in a bearing h attached to the inner front wall of the box,the upper end of this shaft preferably passing through the cover of thebox, as shown in Fig. 6,.vhich thus acts as a bearing for its upper end.Secured to the lower part of the shaft 7L2 is an arm h having a forkedend k which engages on either side of the pin h. Thus as the lever E isrocked to and fro by the motor shaft, a corresponding rocking motionwill be imparted to the shaft 7L2. This shaft has further secured'to ita sleeve it having outwardly extending arms M, k provided at their endswith rollers it (Fig. 4). immediately in the path of these rollers Iarrange stems it upon which suitable applicators can be secured, saidstems passing through long bearings B B the parts B of which fit incorresponding holes formed in the front of the box, as shown in Fig. i.Each stem has a collar 7L fitting the corresponding enlarged portion ofthe bores in the part B a spiral spring 71. being arranged around thestem h between the collar and the bottom of the enlarged bars. Thesesprings thus keep outward so that even if the motor is running the stemsare not acted upon by the rocking arms, unless the applicators arepressed inward as is the case when they are in use.

The applicators are here shown as secured to their stems by set screwsE, and the outer portion of each. stem below the applicator, is screwthreaded to receive a milled disk or nut it. By adjusting the positionof the disk upon the stem the extent of the tapping action or stroke canbe regulated, as will be readily understood Either the disk h or the topof the bearing B 13 can be provided with a surface of leather, rubber orother sound deadening material 71 It will be clear that as the shaft 7Lrocks the arms 7? will alternately strike the stems h and drive themoutward while the springs 72 will return them to their retractedposition ready for the next stroke. The upper end of the shaft h when itis made to pro ject through the box may receive an applicator which willthus have a partial rotatory and frictional movement.

In Figs. 7 to 13 I show a construction whereby the rotatory applicators,secured to the shafts 9 may be arranged so as to have but not to movelongitudinally upon a stem the stems pressed 1;;

of holes 1, 2, 3, and e the fork is inserted in the head 9 the smallestmotion being obtained when the arm 5/ is inserted in l and g in 2, asshown in F ig. 8, and the'greatest when the arm is inserted in f and 5/in 1 as shown in Fig. 13. A spring finger 9 may be employed to securethe forked stem to the stem a g It is evident that a similar arrangementcould be employed for applicators in other positions on the box whethera rotary or semi-rotary motion is imparted to the stem. In Fig. 14: Ishow a modification which could be used instead of the side tappingmechanism shown in Fig. t. Instead of securing a link to the lever D, Imay extend the stem 0 of the side applicator so that its head e willcome within the path of the upper end of the rocking lever E, a springbeing arranged in connection with the stem, as is the case. with all thetapping applicators, to normally keep the heade out of contact with thelever E so that the stem is only operated when pressure is brought tobear upon it from the outside. It will thus be seen that as the leverrocks it will press the stem 6 outward when the lever moves to the right(Fig. 5) the pressure of the patient moving the stem inward as the leverE v outer bearing of said shaft moves to the left. I prefer toprovidetwo such deviceson-e at each end of the motor, the stem at the backofthe motor being suitably operated by an eccentric or cam mounted onthe motor shaft between the and the pinion In Fig. 15 I show an oval'cam j which will give two impulses or strokes to each revolution of theshaft, and in Fig. 1.6, I show a triangular cam j which will give threeimpulses or strokes to each revolution.

It will be observed that in Figs. -'l and 5 I have shown the box ashaving double walls 6, 6 While this construction is not essential it isadvisable as I can fill the space be tween the walls with saw-dust,felt, slagwool or other sound deadening material as it is desirable thatthe apparatus should work as noiselessly as possible. In Figs. 17 to 20I have shown a construction in which the box, which is hung from a cablea on each side of the frame, is held in a balanced position by a weighta secured to the other end of the cable, the weight being convenientlyarranged to move up and down in a hollow standard at forming one sideofthe frame, a central vertical slot (1,12 being formed in the inner wallof the standard for the passage of a lug or angle iron e se- 20, andclamped in any de- To this end a board is boards have central circularopenings in which trunnions is? secured to the sides of the box fit.Each board is is provided with a clamping device for securing the box inany position into whichit may be swung on its trunnions. This clampingdevice may consist, asshown, of a curved block 76 of wood fiber or othermaterial having a central upwardly extending pin between the head In" ofwhich and an inward flange on the tubular guide/e a spiral spring 70 isarranged so asto'normally keep the clamping block out of engagement withthe trim nions M. A lever 0 provided with an eccentric it is pivotedupon the head 7% so that when the lever [6 Figs. 17 and 20 the head andwith it the clamping block 76 is pressed firmly against the trunnion 70and thus holds the box in adjusted position. On raising the lever 70 thebox can be returned to its horizontal po-, sition or otherwisere-adjusted. V

As the box is clear within the two frame iembers it is obvious that itcan be not only tilted but also turned over so as to present any of itsfour sides to the front of the apparatus.

A clamping device maybe arranged to act on both'trunnions a centrallever'common to the two being employed for effecting the clampingaction.

t is obvious that the foregoing'is only one example of the way in whichan apparatus of this kind can be arranged'and constructed, and thatnumerous modifications may be effected while retaining the. broadfeatures of my invention, 71. 6., box or casing containing a motor andaccessory parts operated by the motor shaft the casing containing aplurality of openings for the passage of stems or shafts of applicatorsadapted to be operated by the motor mechanism to produce differentmassage movements or to be operated at different speeds.
